Method for transmitting/receiving data in wireless communication system supporting narrow-band internet of things, and apparatus for same

A User Equipment (UE) transmitting/receiving data in a wireless communication system supporting NarrowBand-Internet of Things (NB-IoT), the UE comprising:

• a transceiver for transmitting and receiving a radio signal;
• and
• a processor connected functionally to the transmitting and receiving unit, wherein the processor is configured to:
• receive a first Narrowband Physical Downlink Control Channel (NPDCCH) through a first search space, wherein the first NPDCCH includes first control information for scheduling a first Narrowband Physical Downlink Shared Channel (NPDSCH) carrying a Single Cell-Multicast Control Channel (SC-MCCH);
• receive the first NPDSCH based on the first control information;
• receive a second NPDCCH through a second search space by using a group identifier acquired through the SC-MCCH, wherein the second NPDCCH includes second control information for scheduling a second NPDSCH carrying a Single Cell-Multicast Traffic Channel (SC-MTCH);
• receive the second NPDSCH based on the second control information;
• and
• when a time period configured for at least one of a third NPDCCH or a third NPDSCH overlaps at least one of the first search space, a time period configured for the first NPDSCH, the second search space, or a time period configured for the second NPDSCH, preferentially receiving at least one of the third NPDCCH or the third NPDSCH,
• wherein the third NPDCCH and the third NPDSCH are channels configured for either paging or random access.
